The V750 smokes the 5400II on this test. Take the V750@2400, add 100% 1.0 0 USM and it's just as sharp (even when looking at 400%) without the nasty grain and it looks much more natural. Use Noise Ninja on the KM to tame the grain and it's mushy. worse than the Epson. @2400 dpi I see no advantage for the KM scanner when I comes to color negs, ISO 400 in particular.
